problem with program given by professor

So my professor gave me a program to upload to my arduino, and I received these errors. What am I doing wrong? It looks exactly like the one he gave us to upload, I have checked it numerous times.

#include<Servo.h>

Servo myservo1;

void setup(){
myservo1.attach(3);
myservo1.writeMicroseconds(1550);
}
void loop(){
}

sketch_sep27c.cpp:1:18: error: Servo.h: No such file or directory
sketch_sep27c:2: error: 'Servo' does not name a type
sketch_sep27c.cpp: In function 'void setup()':
sketch_sep27c:5: error: 'myservo1' was not declared in this scope

There is a great deal of information in the first error message.
All the other messages stem from this.
Where is Servo.h?

Did Professor So do the installation of the IDE?

I don't guess, because I have no clue what the IDE is...

The IDE is the software installed on the PC/Mac/Linux box, that allows you to type in a sketch, compile it and download it.

You might want to add a space between the '#include' and the '<'.

Servo.h: No such file or directory

It is saying it can't find the servo library. This should be installed in the correct folder. see:- Libraries - Arduino Reference

Changing "#include<Servo.h>" to "#include <Servo.h>" (adding the space) fixes the compile error if you have Servo.h in the appropriste folder for the IDE to find it.
